How Installing Energy-Efficient Windows in Castle Pines Saves You Money

When you switch to energy-efficient windows, you may see a few benefits, such as:

  • Decrease your carbon footprint: In Castle Pines, you can reduce your indirect greenhouse gas emissions by about 460 pounds per year after you upgrade to energy-efficient windows.
  • Save on power bills: Switching to energy-efficient windows lowers your energy bills by about 12% because you need less energy.
  • Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, particularly if you have an older home.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Castle Pines

Windows come in various shapes, purposes and styles, so costs and services will differ remarkably depending on your project. Below, we go over the typical cost and services that you’ll find from window installation companies.

How Much Do New Windows Cost?

Typically, homeowners in Castle Pines can expect that most window installations will cost between $250 and $1,200, with the most common installations sitting at around $600. But prices differ remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door replacements, which will make your project cost more.

It’s important to keep in mind that windows with higher efficiency may cost more initially but can save you hundreds of dollars by decreasing your energy bills. Investing in Energy Star certified windows can save Castle Pines homeowners $443+ a year when replacing single-pane windows.

Costs will also vary based on the material you choose for your window frames. Aluminum frames are the least expensive. They’re sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made from wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They’re also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

When it comes to window installations, there are generally two kinds that your provider will have: full-frame and pocket installations.

A full-frame installation is a total window replacement. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves other materials, including insulation and drip edges, which increase the total cost of the project. Also worth noting: you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations are on the simpler end and won’t cost as much because they involve merely replacing the window within its existing frame. But if the frame has any damage or rot, you may have to get a full-frame installation instead.

If you’re unsure which window installation service you should get, your installer can advise you. In general, the choice is based on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Castle Pines

EcoWatch differs from most reviewers because we examine these companies through a sustainability lens. Along with energy efficiency, we assessed several window installers in Castle Pines and ranked them based on the following methodology:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve the Castle Pines area so you can find a quality window installation company near you.

Work Quality

When picking new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the type of window you choose. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If most customers don’t have positive feedback about their service from a certain window installation company, you won’t see it featured on EcoWatch.

Cost

This one is a give-and-take: as with other services, cheap window companies are not going to provide the highest quality service. On the other hand, we want to ensure we’re highlighting companies that provide a range of price and financing options so they’re accessible to most homeowners.

Warranty

Protecting your investment in new windows is important to many homeowners. That’s why window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a proven track record in the industry. Window installers that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Castle Pines, CO Window Replacement FAQs

How much does window installation cost?

The average cost of replacing one window can range between $450 and $650. There are a variety of factors that affect the cost, which include how energy-efficient the windows are, the number of windows, local labor costs, the materials used in designing the windows, styles and sizes of windows and your property’s location.

Which kind of window is the best?

A window’s energy efficiency is influenced by a variety of factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient since they are certified by the U.S. Department of Energy.

What do window installers do?

Window installers travel to your property to remove your old windows and replace them with new ones. Some providers install products distributed by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation.

When is the best time of year to replace windows?

While you can install windows any time of year, warmer weather is typically better for replacing windows. In addition, it shouldn’t be raining, as rain can make the installation more difficult.

Should I replace my windows all at once?

If your windows are greater than 20 years old, it’s most likely time to replace all of them. At that point, they are typically less efficient, leakier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less stress.
